We started the week off with Sprint posting an update to its Nexus 5 software version page, advising users that a new release was incoming. While the initial build number of KTU48F it gave was confusing, that turned out to be a typo, later corrected to KTU84F. We had already associated recent builds like this with Android 4.4.3, and the carrier sure seemed to be confirming that a release was imminent. But then Tuesday came with no update… as did Wednesday and Thursday. With the week winding down, is KTU84F still on the horizon? Not according to Sprint, which has reverted its Nexus 5 software page to remove any mention of the update.

So, what happened? Did Sprint get its wires crossed and misunderstand when Google was making its software available? Did some unexpected bug pop up at the last moment and force Google to scrub its plans? Without some internal source coming forward, we just can’t say.

Maybe Android 4.4.3 will arrive next week. Maybe it won’t show until May. But based on the evidence we’ve seen, Google’s been testing it for a while now, and seeing as it’s supposed to deliver a collection of bugfixes, instead of implementing new features, we’re imaging it shows up sooner rather than later.
